Coconut shell carbon for chlorine, taste, and odor removal. Ideal for bottled water and beverage pre-treatment.
Sediment pre-filtration for RO systems. Protects membranes. 1-50 micron. Food grade polypropylene.
4040 and 8040 elements. Removes 99.5% dissolved solids. Essential for bottled water and food processing.
Filtration in a food or beverage plant is not just a water quality question, it is a compliance question. If your product crosses a border or sits on a supermarket shelf, the filter media in contact with the process water is a food-contact material and is regulated as such. In practice that means FDA 21 CFR 177 compliance in the United States, EU 1935/2004 and 10/2011 in Europe, and evidence of NSF/ANSI 42 and 53 certification for whatever reduction claim you put on the label.
The failure mode is not usually an unsafe product, it is a supplier who cannot produce the material compliance documentation when an audit or a customer questionnaire lands. Ask any cartridge supplier for the food-contact declaration before you place the first order.
Most beverage lines run the same three-stage logic. Sediment pre-filtration protects everything downstream from suspended solids and extends the life of the expensive media. Carbon block then removes chlorine, chloramine and the organics that cause taste and odour defects - and, critically, protects RO membranes from chlorine oxidation. The final stage polishes the water to the specification the product requires, whether that is 1 micron absolute for a soft drink line or full reverse osmosis for bottled water.
Two industries add a fourth consideration. Breweries care about the mineral profile of the brewing water as much as its purity, so RO is blended back with untreated water to hit a target profile. Dairies and soft drink producers run hot CIP cycles that will destroy a standard polypropylene cartridge, so the media must be rated for the cleaning temperature, not just the production temperature.
| Application | Stage | Recommended cartridge | Rating |
|---|---|---|---|
| Bottled water | Pre-filtration | PP melt blown | 5 µm |
| Bottled water | Organics / chlorine | Carbon block | 1-5 µm |
| Bottled water | Dissolved solids | RO membrane | 4040 / 8040 |
| Carbonated soft drinks | Pre + polish | PP melt blown | 1-5 µm |
| Brewery (brewing water) | Pre + RO blend | PP + RO | 1 µm / RO |
| Dairy | Pre-filtration (hot CIP) | PTFE or high-temp PP | 5-10 µm |
| Juice / concentrate | Clarity | PP melt blown + carbon | 1-5 µm |
| Ingredient water | Full treatment | PP + carbon + RO | 0.5-1 µm final |
Change cartridges on differential pressure, not on the calendar. A 1.0-1.5 bar rise above the clean differential is the normal trigger. In continuous bottling that often means a change every four to eight weeks; in brewery or dairy service with heavier organic loading it can be every two to four weeks.
Record the change-out date, the differential pressure at change, and the batch numbers of the cartridges fitted. That record is what turns a filter change from an operational guess into something you can show an auditor. It also tells you, over a few months, whether your replacement interval is set correctly or you are throwing away media with life left in it.
The materials should meet FDA 21 CFR 177 requirements for food contact and carry NSF/ANSI 42 and 53 certification for the reduction claims being made. For European production, EU 1935/2004 and 10/2011 food-contact compliance is required. Ask for the material compliance statement, not just a product brochure.
Most lines run three: sediment pre-filtration (5-25 micron PP melt blown) to protect downstream membranes, carbon block for chlorine, taste and odour removal, and a final polishing stage (0.5-1 micron or RO) before filling. Bottled water typically adds RO and sometimes UV.
For bottled water treat the source water to meet the relevant standard for the end product. Typical configuration is 5 micron PP sediment pre-filtration, carbon block for chlorine and organics removal, then RO for dissolved solids, with a 1 micron absolute final filter before filling.
Change on differential pressure, and never let a cartridge exceed its rated service life. In continuous bottling lines that is often every 4-8 weeks; in brewery or dairy service with high organic load it can be every 2-4 weeks. Record the change-out date and differential pressure every time - auditors ask for it.
No. Carbon block removes chlorine, chloramine, taste, odour and some organics by adsorption. It does not remove dissolved minerals or salts - that requires reverse osmosis. If mineral content matters for your product, carbon block is a pre-treatment, not a final treatment.
Standard polypropylene cartridges are rated to about 80°C. Hot-fill and CIP cycles that exceed that need high-temperature media such as PTFE. Check both the continuous operating temperature and the peak temperature during cleaning before specifying.
